Comparison of methods for calculating water erosion.
MURČO, Tomáš
Bachelor thesis presents a comparison of methods for calculating water erosion. The aim is to summarize available evidence concerning the problems of water erosion. There are presented some methods how to calculate average annual erosion of soils, and selected models for calculating the erosion immediately. There are also listed possible erosion control measures through which we can at least slow the effects of erosion, rather than stop completely.

Zpřesnění modelu odhadování vývoje cen na komoditních trzích za pomocipřidání nových kanálů
Kozmík, V. ; Šindelář, Jan
Present work deals with a problem of price prediction on futures markets. Main goal of this work is to find out on which input channels (price,volume of contracts, etc.) depends the sought future price. We make further simplications to be able to present the problem as a mathematical one, which can be solved using Bayesian estimation methods. In this work we present the process of price prediction and then concentrate on the main aim, which is structure determination. Applied algorithm is described mathematically and also programmed in Matlab environment. The results of the algorithm on specific data and their economic interpretation are the last part of this work.

Chaotic time-series prediction
Dědič, Martin ; Tichý, Vladimír (advisor) ; Smrčka, Pavel (referee)
This thesis focuses on possibility of chaotic (specially economic) time-series prediction. Chaotic time-series are unpredictable in long-term due to their high sensitivity on initial conditions. Nevertheless, their behavior should be more or less predictable in short-term. Goal of this thesis is to show, how much and if any prediction, is possible by non-linear prediction method, and try to reveal or to reject presence of chaotic behavior in them. Work is split into three chapters. Chapter One briefly introduces chosen important concepts and methods from this area. In addition, to describe some prediction methods, there are outlined which indicators and methods are possible to use in order to find possibilities and boundaries of this prediction. Chapter Two is focused on modifications of FracLab software, which is used for create this prediction. Last chapter is experimental. Besides the description of examined time-series and methods, it includes discussion of results.

Principles of trading on betting exchanges
Karásek, Michal ; Málek, Jiří (advisor) ; Moravec, Lukáš (referee)
Unlike traditional stock exchanges, where bonds, shares and financial derivatives are traded, on the betting exchanges there are traded probabilistic estimates of the results of sporting or social events. The market price of bets, namely the market implied probability is influenced by estimate of the outcome. The specificity of betting exchanges is also a short period to maturity of contracts, and the possibility to trade with the estimated result of one real world event in several sub-markets simultaneously. In theoretical analysis, we have defined the bet, the underlying asset, and the binary betting contract, which is traded on betting exchanges. We have described some practical aspects of trading. Properties of the probabilistic contracts are demonstrated on several examples. Finally, we constructed the mathematical model of a tennis match, which is based on a binomial valuation model. This allows us to compare the market price of a contract with the price recommended by the model.
